Embodiment Construction

[0035] Aiming at the problem that the existing technology cannot trace the source of PDF files well, the embodiment of the present invention uses the function of the two-dimensional code watermark to paste an invisible business card on each PDF file, so as to realize the traceability of the PDF files , in order to minimize the security risks caused by leaks to user data. The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The embodiment of the present invention provides a method for tracking the circulation of PDF files, see figure 1 , the method includes:

[0037] S101. Generate an invisible two-dimensional code watermark uniquely corresponding to the PDF file;

[0038] During specific implementation, the embodiment of the present invention...

Abstract

The invention discloses a tracking method for PDF (Portable Document Format) file circulation, which is characterized in that when a user operates a PDF file, an invisible two-dimensional code watermark can be generated without feeling of the user, and the invisible two-dimensional code watermark can record all circulation information of the PDF file from creation to subsequent use so as to realize the purpose of tracing the PDF file. Therefore, the problem of potential safety hazards caused by secret divulgence to user data is relieved to the maximum extent.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a tracking method for PDF file circulation. Background technique [0002] With the continuous development of office automation, people's requirements for the security of various electronic documents generated in the office process are also constantly increasing. However, once the electronic documents are leaked, it is difficult to reverse the source, such as the commonly used PDF files. , in a specific environment, it is basically impossible to trace PDF files and obtain the circulation path of PDF files. Therefore, how to trace the source of various electronic files to minimize the security of user data caused by leaks Hidden dangers have become a problem that needs to be solved urgently. Contents of the invention [0003] The invention provides a tracking method for the circulation of PDF files to solve the problem in the prior art that the source of PDF files cannot be we...
